co ordinate grid problem

Question

Plot these points on a coordinate grid: A(–2, 3), B(–4, 0), C(–2, –3), D(2, –3) Join the points to draw quadrilateral ABCD . b) Draw the image of quadrilateral ABCD after each transformation: i) a translation 7 units left and 8 units up ii) a reflection in the x-axis iii) a rotation of 90° counterclockwise about the origin c) How are the images alike? Different? first i plotted these points and draw a quadrilateral ABCD then i translated the fig ABCD and got these points A' (-9 , 11)  B' (-11,8) C' (-9,5) D'(-5,5)

now i should reflect ABCD or A'B'C'D' in the x axis ??

and please tell me the ans of part c

thanx

Answer 1

Because (i), (ii) and (iii) are part of (b), I think you should follow the transformations through. So you reflect A'B'C'D' to give you A"B"C"D", then rotate A"B"C"D". When you get to part (c) you will be able to appreciate what the final image looks like compared to the original ABCD. Certainly, you should calculate the coordinates as well as drawing so that you can check the accuracy of your drawings.
